How to simulate damage variance ranges with your AI

Connect your combat math to your agent. It will run the numbers to show you exactly how much damage your players will hit for, from the worst luck to the best.

Short answer

How can I test my damage math for combat?

Your agent uses the simulate_damage_variance tool to run repeated trials of your specific combat formulas. You'll get the full range of possible outcomes, from the lowest possible roll to the highest. This breakdown shows you the spread of your damage math.

Simulation outcomes

What you get from the simulation

The agent processes your formulas and hands you these specific results.

MINIMUM

The floor

The agent calculates the absolute lowest damage possible. This tells you if a boss fight might become trivial if the player rolls poorly.

MAXIMUM

The ceiling

The agent finds the highest possible damage spike. Use this to see if a single lucky roll could accidentally one-shot an enemy.

SPREAD

The variance

The agent identifies the gap between the low and high ends. This shows how much luck actually matters in your specific combat system.

HUMAN

Manual tuning

The agent provides the raw numbers, but you decide if the math feels right. You'll need to adjust the formulas yourself if the variance is too wild.

The workflow

What your AI does when the formula arrives.

The agent takes your raw math and turns it into a statistical range.

  1. Parse the math

    The agent reads your damage formulas and identifies all variables, modifiers, and dice rolls involved.

    simulate_damage_variance

  2. Run trials

    The agent executes the math repeatedly to account for every possible combination of dice results.

  3. Identify extremes

    The agent isolates the specific rolls that lead to the minimum and maximum damage values.

  4. Report range

    The agent presents the final damage bounds so you can see the full spectrum of combat outcomes.

FAQ

How the simulation behaves

  • 01

    Can the AI change my damage formulas for me?

    No. The agent can only run simulations based on the math you provide. You must manually edit your formulas if you want to change the results.

  • 02

    Does it account for critical hits?

    Yes, as long as your formula includes the logic for critical multipliers.

  • 03

    Will the AI save these results to my game files?

    No. The agent performs the calculations and gives you the answer in chat. It does not write to your local files or databases.

  • 04

    How many trials does it run?

    The agent runs enough trials to capture the absolute minimum and maximum possible outcomes defined by your dice and modifiers.

  • 05

    Can it simulate damage for an entire party at once?

    Yes, if you provide the formulas for each party member in your prompt.
